JOURNAL LUBRICATOR Application filed November 12,1927/ My invention relates to journal lubricators of the type particularly adapted foruse in railway rolling stock and consists of a device including a lubricant reservoir and a member, actuated by relative movement of the device and the journal, for feeding a lubricant applicator from the reservoir to the journal.

The object of my invention is to provide a feeding mechanism which will be certain in operation and will supply lubricant 'to the journal by means of a moving belt as distinguished from pumping a stream of lubricant to the journal.

In the accompanying drawings which illustrate my invention- Figure 1 is a section through a driving box cellar including my device and the adjacent journal and hub with which the device is assembled.

Figure 2 is a transverse section taken substantially on the line 2-2 of Figure 1.

A journal A indicated in Figure 1 isprovided with a wheel B, the hub of which extends radially of the journal and the journal supports the truck or frame of the locomotive or other rolling stock to which it is applied in any ordinary manner the details of which part of my invention and are not on line 5-5 of Figform no illustrated but which will include a pedestal within which the cellar is carried as is well understood in the art.

cellar includes a bottom 1 and side walls e lower portion of which cellar forms a reservoir for lubricant 3. I prefer to'use an endless belt 4 as the means for supplying lubricant-to the journal, and in the preferred form illustrated in Figures 1 2 and 3 this belt is shown as passing over rollers 5, 6 and 7. Roller 5 is j ournaled in brackets 8 formed integrally with one of the side walls 2 of the cellar. 'Roller 6 is journaled on yielding elements 9 mounted on the other side wall of the cellar and roller 7 is hollow throughout its r length and is j ournaled upon a rod 10 which extends through the end walls 11 and 12 of the cellar and is adapted to be reciprocated.

lengthwise and may be termed a contact rod as itsouter end 13 is adapted to contact with the hub B on the wheel of the journaL. The opposite end 14 of rod 10 is squared and is received in a cap 15 provided with a spring 16 which tends to thrustrod 10 to the left.

In all railway journals of this type there is substantial play of the axlelengthwise in its 8 boxand I utilize this play of the axle to move the contact rod 10in one direction, spring 16 functioning to move the rod in the opposite direction whenever the movement of the j ournal so permits.

To translate this the rod into rotary movement of roller 7, I provide the surface of the rod with a series of short fixed ribs or blades 17 inclined to the axis of the rod. The adjacentrportion of roller 7 is enlarged to form a housing as indicated at 18. A 'series'of pawls 19 are provided on the sides of this housing and are spaced unevenly about theinner periphery of reciprocal movement of housing 18 so that at least one of the pawls 19 w ll always be engaged by Movement of the rod'10 to the left will rotate at least, one pawl on its pivot until the end of the pawl engages the inner periphery of the housing 18 when further movement of the rotate the roller 7 about the axis of the roller and rod. A ratchet and pawl 20 is arranged to check return movement of the roller and insure the same being advanced continuously in one di- '18015101'1.

Preferably roller 7 is provided with teeth one of the ribs 17.

21 or similar elements for engaging belt 4 and moving the latter. The movement of the belt through the lubricant reservoir and over rollers 5 and 6 will carry lubricant to the journal A, the bottom of which is below the level of the tops of rollers 5 and 6. The yielding mounting 9 for roller 6 will place the belt under suitable tension and this tension may be made any degree desired.

In order to avoid the wasteful discharge of surplus lubricant, I prefer to provide wipers 22 in the form of rollers yieldingly held in contact with the journal A, by means of springs 23, and positioned above the level of rollers 5 and 6.

My invention may be embodied in numerous forms and I illustrate one of such modifications in Figures 4 and 5 in which the lubricant reservoir 24 is provided with an extension 25 in which is mounted a weight 26 yieldingly supported by a spring27 and provided with an upstanding element 28 car-' rying a pair of pawls 29 adapted to engage opposite sides of a ratchet 30 which is carried on a shaft 31 mounting a roller 32 corresponding to the roller 7 shown in Figures 1, 2 and 3. c

This device, instead of relying upon the lateral movement of the journal in its cellar, is actuated by the successive impulses, given to the weight 26, caused by vertical jars such as results from a wheel passing over a rail joint and the complementary movement of the weight by the spring 27.

In the structure shown in Figures 6 and 7 I utilize a swinging pendulum 33 pivoted at 34 on a bracket 35 and this pendulum is provided with flexible arms 36 adapted to engage the teeth of a ratchet 37 mounted on the shaft 38 of a roller 39 which is adapted to rotate the lubricating belt similar to that shown in Figures 1, 2 and 3. This operating mechanism is mounted in a compartment 40 corresponding to compartment 25 shown in Figures 4 and 5. i

The swaying of the truck with which the device is assembled will cause oscillating movement of the pendulum 33 resulting in alternate upward and downward movement of the arms 36 and resulting rotation of ratchet 37. V

In each of the structures shown in Figures 4 to 7 there will be no necessity of a check ratchet and pawl as the devices are doubleacting and feed the roller irrespective of the direction of movement of the weight 26 over the pendulum 33. V p '1 I V In the structure shown in Figures 8, 8a, and 9, the side walls 41 of the cellar are provided withfixed brackets 42 on which are mounted idler rollers 43 and the lubricating belt 44 passes over rollers 43 and-carriesa third idler roller 45, the weight of which holds the horizontal portion of the belt against the undersurface of the journal J thereby decrease and, as the amount of lubricant on the surface of the journal decreases, friction between the journal and the belt will result in the belt being driven by the journal so as to feed lubricant from the reservoir to the journal.

The ends of roller 45 are provided with flan ges 46 which retain the roller in position and I prefer to provide a rib 47 on the bottom wall of the cellar, adjacent the inner face of one of the flanges 46, and to provide a spring 48 bearing against the opposite face of the flange 47. In this manner, I can fric- 7 tionally retard the rotation of roller 45 and the amount of lubricant which is delivered to the journal.

In the structure shown in Figures 101and 11, I utilize a pendulum but instead of the same swinging longitudinally of the journal, it is arranged to swing transversely thereof and it is therefore actuated by uneven movements of the truck along the rail, instead of movements across the rail. In this struc ture, the pendulum 49 is suspended from the top wall of the compartment 50 at the side of the cellar and pawls 51 and 52 are pivoted on the pendulum supporting element 53 and engage opposite sides of a ratchet 54 mounted on the end of the belt of the feeding roller 55. Movement of pendulum 49 tothe '4 right will result in rotation of ratchet 54 and roller 55 through the action of pawl 51, pawl 52 riding over the upper teeth of the ratchet. Movement of pendulum direction will rotate ratchet 54 and roller 55 in the same direction, pawl 51 riding over tne lower teeth of the ratchet.

Obviously, other variations in structure could be accomplished without departing from the spirit of my invention, and I contemplate the exclusive use of all such modifications as come within the scope of my claims.
